  • 简介:极端暴风雨在13172013年12月期间撞击了南部的中国,与破记录的每日的降雨率,大空间程度,和不平常地长的坚持。我们检验了什么导致了这重降雨进程,基于通过合成、诊断的方法的观察降雨数据和NCEP-NCAR分析数据。结果证明在副热带的西的喷气以内的Rossby波导引起了事件。Rossby波浪在东方地中海上从强壮的冷空气侵入发源进副热带的西的喷气。中东西的喷气与改进并且向北方变,宣传的Rossby波浪慢慢地东方并且加深了印度缅甸马槽,它从孟加拉和华南海的海湾把大量潮湿搬运了到南部的中国。在上面的对流层的强壮的分叉,由东方亚洲西的喷气的改进引起了,也在东南中国上赞成了重降雨过程。另外,Rossby波浪与negative-to-positive阶段移动和诺思大西洋摆动的改进被联系,但是在东方地中海的集中在副热带的西的喷气以内在Rossby波浪的东方繁殖起了关键作用。
